Founded in 2000 on the principle that all young people -- not just those with resources -- should have access to quality arts learning opportunities, Arts Corps is now a leading nonprofit arts education organization in Seattle. Starting with just a few classes at six sites, Arts Corps now serves over 2,000 K-12th grade students a year at approximately 40 sites. Arts Corps places after-school classes and in-school residencies primarily at schools and community centers serving low-income youth who often have few other opportunities for arts learning. Programs cover the spectrum of arts disciplines from dance to visual arts to photography to music, and include popular classes such as Brazilian dance, theater, comic illustration, spoken word, sculpture and more. Programming is designed to foster artistic competencies and creative habits of mind such as imagination, healthy risk-taking, reflection, persistence and critical thinking. The program operates on a school year, with select workshops occurring in the summer months. Arts Corps has conducted program evaluation since inception and has refined its focus each year to better explore and describe the impacts of arts classes on students.
